Normally it is good to use the actual software (Quartus II 4.2)? Which Nios version are you using?

So you are not able to configure the FPGA with your sof-File? But Quartus II is detecting your device? Did you change the programming of the configuration CPLD (EPM7128)?

Is that the explanation for about flash (http://www.niosforum.com/forum/index.php?act=st&f=2&t=667)?
